Machine learning can play an important role in fraud prevention at financial institutions, says Marc Trepanier of ACI Worldwide, who addresses the challenges involved.

"Machine learning is one of the tools that you should be using as part of a multifaceted fraud strategy," Trepanier says in an interview with Information Security Media Group. "There are lots of tools in the toolkit of fraud people. ... They have all these things they use to try to solve the problem around fraud, but you need the right data. To get the value there, you need to have multiple inputs. You have to have an intelligence network and the location to gather all that network intelligence."
